The photograph captures the geometric facade of the Museum August Kestner in Hannover. A symphony of small windows composes the building’s exterior, creating a patterned mosaic that rhythmically repeats across the surface. Amidst this uniformity, a singular large window punctuates the design, offering a glimpse into the world within. It frames a reflection of the outside, blurring the boundaries between the museum’s interior and the external environment. This architectural feature not only disrupts the pattern but also invites contemplation about the interplay of space, perspective, and the art of display inherent in museum design. A large window between small windows in the facade of the building of the Museum August Kestner, a glass and concrete facade from 1961. The original old museum building still exists today in a special form. Its partial destruction by bombing in the Second World War was countered by a remodeling between 1958 and 1961. Since then, a conversion and extension with a glass and concrete facade with around 5,000 windows has enclosed the remains of the building. This concrete cube is now a listed building. Today, with its design collection, it is one of the most important museums of applied art in Germany The museum's namesake, August Kestner, lived and worked in Rome for 36 years as a Hanoverian envoy. There, as a private collector, he amassed a considerable number of Egyptian and Greco-Roman artifacts as well as other works of art. After his death, his nephew, Hermann Kestner, received the collection with the task of handing it over to his home town of Hanover and making it accessible to the public.
